Research ArticleOpen accessIn the abstractExtending the Concepts of Normalization from Relational Databases to Extensible-Markup-Language Databases ModelH.J. F. El-SofanyIn this study we have studied the problem of how to extend the concepts of Functional Dependency (FD) and normalization in relational databases to include the eXtensible Markup Language (XML) model. We shown that, like relational databases, XML documents may contain redundant information and this redundancy may cause update anomalies. Furthermore, such problems are caused by certain functional dependencies among … …Journal of Computer Science, Vol. 4, Issue 9 · 30 Sep 2008 · 6,461 accessesView PDF Cite

Research ArticleOpen accessIn the abstractUtilization of AODV in Wireless Ad Hoc NetworksZeyad M. Alfawaer, GuiWei Hua, Nidal A. HamdehAODV is a mature and widely accepted routing protocol for Mobile Ad hoc Networks (MANET), it has low processing and memory overhead and low network utilization, and works well even in high mobility situation. We modified AODV to use these dominating sets, resulting in the AODV-DS protocol. Our contribution in addressing the fragility of a minimum connected dominating set in … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 7,160 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Meaning of a Redundant Codon: There is Protein Folding Information in Nucleic Acids in Addition to the Genetic CodeJan C. Biro, Josephine M.K. BiroAll the information necessary for protein folding is supposed to be present in the amino acid sequence. It is still not possible to provide specific ab initio structure predictions by bioinformatical methods. It is suspected that additional folding information is present in protein coding nucleic acid sequences, which is not represented by the known genetic code. Nucleic acid subsequences comprising … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 1 · 31 Mar 2006 · 8,292 accessesView PDF Cite
